+High-Throughput Speed Benchmark Suite: 50 Questions Per Language (750 Queries Total).
+
+Tests pure in-scope knowledge retrieval, re-ranking, and context synthesis speed
+across all 15 Indic languages:
+['as', 'bn', 'gu', 'hi', 'kn', 'ml', 'mr', 'ne', 'or', 'pa', 'sa', 'ta', 'te', 'ur', 'en']
+
+NO guardrail tests, NO off-topic questions — pure pipeline speed evaluation.
